The 2496 works in 24-bit (I think), so you need rate conversion on-the-
fly.  ALSA does this with the "plughw" plugin, so if you change the
above command to 

	aplay -D plughw /sound-sample.wav

you should get sound.  Maybe someone else can explain further, as I have
had problems changing my "default" plugin so that ALSA can work
seemlessly with all my non-jack apps.  I just play dumb and use jack as
much as possible. :-)
